Capsuling bottle and apparatus therefor



Dec. 31, .1935. A. G. ENOCK CAPSULING BOTTLE AND APPARATUS THEREFORFiled Jan. 18, 1954 Patented Dec. 31, 1935 UNITED CAPSULIN G BOTTLE ANDAPPARATUS THEREFOR Arthur Guy Enock, Wembley Park, England ApplicationJanuary 18, 1934, Serial No. 707,147 In Great Britain February 2, 1933 1Claim.

This invention relates to a method of and apparatus for capping orapplying capsules to bottles more particularly to such as have a beadround the outer edge of the mouth.

In my application for Patent No. 670,325 filed May 10, 1933, I havedescribed a method and apparatus by which a cap or capsule out in sheetor disc form is fed into position over the bottle mouth, is partlyformed thereon and finally is, in situ, shaped to and secured around thebead of the bottle mouth.

The object of this invention is to provide means whereby the caps may befed to the bottle capas distinct from being fed from a magazinecontaining a number of cap pieces previously cut to size and shape.

According to the invention the capping machine is constructed with feedrollers to feed forward the material, a punch by which the cappiece issevered from the material, means by which the severed cap-piece isplaced in approximately a flat state in position over the bottle mouthand a folding die and crimping appliance such as described inapplication No. 670,325.

The invention will be fully described with reference to the accompanyingdrawing:-

Fig. l is an elevation of cutting punch in advance of the capping head.

Fig. 2 is a plan of Fig. 1.

Fig. 3 is an elevation with cutting punch placed concentrically with thecapping head.

Figs. 4 and 5 show an alternative form of blank holder.

Referring to Figs. 1 and 2 the apparatus is constructed with a die orpunch E adjacent to the capping head K and feed rollers G, G. A transferarm H with a suction nozzle P and pipe h is mounted adapted to receivethe stamped out cap-piece and transfer it to position in the recess isbelow the capping head above the bottle mouth. The transfer arm H may beoperated by a cam H synchronizing with the means round the tensionroller B and guide roller C and is fed by the feed rollers G and G tocorrect position with relation to the cutting dies or'too'ls The blankcap piece is here cut by pedestal of known the tools E and E and whilestill approximately flat and unformed is deposited on or removed by thesuction nozzle P of the transfer arm H. This arm moves until it is underthe capping head K and deposits the blank cap piece on to the suction 5holder J in the capping head K or inthe recess is below the cappinghead. From this position the blank is formed to shape and attached tothe bottle as described in my specification No. 670,325. The feedrollers G and G may also emboss the 0 material as it passes between themor a separate pair of embossing rollers 'D and D may be provided. Thescrap material S from which the cap-pieces have been cut is re-wound atspool R.

A modified form' of the transfer arm H is shown 15 in Figs. 4 and 5constructed with an open or hollow tray L upon which the blank cap-pieceis deposited after being cut and moved to a position head K, the bottlemouth passing through the open or hollow tray L as it rises.Alternatively the action of the. transfer arm H and the tray L maydeposit the cap on the suction attachment J of the capping head in whichcase the tray is 25 returned away from the capping head before thebottle rises.

In the construction shown in Fig. 3 the punch and cutting dies Q andQare placed concentrically round the capping head K which is fitted 30with a suction nozzle J to retain the cap-piece in position untilapplied to the bottle mouth. The cutting is preferably performed by thetool Q rising against the edge of the tool Q as the bottle N risesthough the tool Q may be depressed si- 35 multaneously with the risingof the bottle N. The material F is fed through as before described fromthe reel A by the feed rollers G, G into the capping head and is cut insitu over thebottle mouth by the tools Q, Q The severed 40 cap pieceadheres to the tools, or to the suction nozzle J placed in the cappinghead, until removed by the bottle as it rises into the capping head K.

What I claim as my invention and desire to 45 protect by Letters Patentis:-

In a machine. for capping bottles with flat disc shaped caps thecombination with the capping head of a punch adjacent thereto to severcap pieces in succession from a strip of material, a 50 pivoted transferarm below the punch, a suction nozzle thereon by which the punched discis held and transferred from the punching head -tothe capping head, acapping plunger in the capping head, and a suction nozzle. centrallydisposed 55 within the plunger to receive the disc from the transferringarm and hold it on the bottle mouth during the capping operation.
